In more detail, the sliding type massage apparatus is configured so that an auxiliary portion supporting a lower body of a user slidably moves from a body portion supporting an upper body of the user and thus the auxiliary portion maintains horizontality while moving. To this end, there is provided a sliding type massage apparatus including a body portion configured to support an upper body of a user and an auxiliary portion connected to the body portion to be slidable in a longitudinal direction to support a lower body of the user. Here, the body portion includes first support members which are rotatable to support a bottom surface of the auxiliary portion when the auxiliary portion slides. ## Claims ### Claim 1 A sliding type massage apparatus comprising: a body portion configured to support an upper body of a user; and an auxiliary portion connected to the body portion to be slidable in a longitudinal direction to support a lower body of the user, wherein the body portion comprises first support members which are rotatable to support a bottom surface of the auxiliary portion when the auxiliary portion slides and second guide members which are extending in the sliding direction of the auxiliary portion, wherein second support members, which are rotatable to move along the second guide members while the auxiliary portion slides, are provided on the auxiliary portion, wherein first support bars are formed on the body portion to extend in a lateral direction toward the auxiliary portion to allow the first support members to support the bottom surface of the auxiliary portion, wherein second support bars are formed to allow the second support members to be inserted into and disposed in the second guide members, and to extend so that the first support members and the second support members are disposed at a different position along the lateral direction. ### Claim 2 (depends on 1) The sliding type massage apparatus of claim 1, wherein the body portion comprises a first plate configured to directly support the upper body of the user and side frames configured to support both sides of the first plate, and the first support members are provided on inner surfaces of the side frames. ### Claim 3 (depends on 2) The sliding type massage apparatus of claim 2, wherein the auxiliary portion comprises a second plate configured to directly support the lower body of the user and a support leg configured to support the second plate to maintain horizontality in use, and first guide members supported by the first support members and extending in the sliding direction of the auxiliary portion are provided on a bottom surface of the second plate. ### Claim 4 (depends on 3) The sliding type massage apparatus of claim 3, wherein the second guide members are provided on the inner surfaces of the side frames. ### Claim 5 (depends on 4) The sliding type massage apparatus of claim 4, wherein the second guide members each comprise a parallel movement section formed to allow the auxiliary portion to move while being parallel to the ground. ### Claim 6 (depends on 5) The sliding type massage apparatus of claim 5, wherein the second guide members each comprise an opening-prevention section extending downward from one side of the parallel movement section and a closing-prevention section extending downward from an other side of the parallel movement section, and wherein the first support members are provided on the other side of the parallel movement section. ### Claim 7 (depends on 6) The sliding type massage apparatus of claim 6, wherein when the auxiliary portion is disposed above the body portion, the second plate is disposed above the first plate by as much as a first height, and wherein the closing-prevention section is formed to extend downward by as much as the first height. ### Claim 8 (depends on 7) The sliding type massage apparatus of claim 7, wherein when the auxiliary portion is disposed above the body portion, the support leg is spaced upward from the ground by the first height. ### Claim 9 (depends on 8) The sliding type massage apparatus of claim 8, wherein rotatable third support members are provided on a bottom end of the support leg to support the auxiliary portion when the auxiliary portion slides. ### Claim 10 (depends on 4) The sliding type massage apparatus of claim 4, wherein the first support bars are provided on the inner surfaces of the side frames to allow the first support members to support the bottom surface of the auxiliary portion. ### Claim 11 (depends on 10) The sliding type massage apparatus of claim 10, wherein the second support bars are provided on the bottom surface of the second plate to allow the second support members to be inserted into and disposed in the second guide members.
